This question already has an answer here:
I know that that duplicate questions automatically post the duplicate to the comments on the question.
Would it be possible / a good idea to have this for all vote closes? Possibly having a check box at the bottom of the vote close window to post reason as a comment to the question might work as well.
My reasoning for this is I tend to vote close questions for lack of effort.
unclear what you're asking - Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question.
Now in some cases the question could be improved, but a lot of times questions like this are by new users who don't always return. If I feel it can be improved I like to let these new users know that it was vote closed and why. I copy that to the comment. example: Google Analytics for Android: Still can't Enable Demographics and Interests
Is this something we could consider adding?
